What is Protein?
Food has protein but foods with the most proteins are chicken, fish, and cheese.
Proteins is made of amino acids.
Proteins helps build muscle tissues and helps function the bodies tissue & organ.
Monomer and Polymer
Proteins are Polymer
Where can we find Proteins?
Human body - Everywhere in the body
Functions of Proteins
2. carry oxygen (hemoglobin)
3. build structure such as hair, nails, and horn.
4. Contract muscles
5. carry on active and facilitated transport.
6. makes up the cytoskeleton- microfilaments, microtubules
The 4 Levels of Structure
Primary - Is a protein structure of numbers and identity of the component of amino acids in the protein. 20 different amino acids. Proteins build up from a set number of amino acids.
Secondary - The usual way in which the polypeptide chain is coiled is called the alpha helix, which interactions take place between groups 3-4 of amino acid. The beta pleated sheet is another regular secondary structure.
Tertiary - 3 dimensional structure of a protein polypeptide chains locked in place by other stronger bonds.
Quaternary - Not all proteins have quaternary level of structure. Consists of more identical sub-unit, not joined by strong bonds. (Hemoglobin) = oxygen
